Pushing seems to indicate a strong flush draw (either nut flush draw or oesf draw). If you had flopped a set/two pair, would you just push here? I doubt that.

Make a 2/3 pot-sized raise. If he pushes, then you have a decision to make about whether or not you want to gamble. If he simply calls, you have position on any turn and can easily check behind if you don't improve.
